Esaias is very bold; i.e. he speaks more boldly concerning the calling of the Gentiles, and the casting off the Jews. He used a holy freedom, though it cost him dear; Jerome saith, he was sawn asunder with a wooden saw. This is a commendable property in a preacher: see Acts 4:13, Acts 28:31. And saith: viz. in Isaiah 65:1. The apostle in this citation differs in some words, both from the Hebrew text and the Seventy, as may appear to him that will compare them together. I was found of them that sought me not; compare this with Romans 9:30, and see the notes there. I was made manifest unto them that asked not after me; compare this with Ephesians 2:2. The advantage and advancement of the Gentiles was altogether of free grace, and an effect of God's free election.
